Default Time Dependent Temperature Dependent BC Analysis
Posts: n/a

I have a peculiar problem to resolve. I have a heat source whose Q is dependent on its Centroid Temperature. To cool this heat source, I have a fixed cooler. I can perform a steady state analysis for the same. Fine upto this point.

But If I want to perform a transient analysis, with the same Q being dependent on time also, Is it possible? Does it physically make any sense. I believe I am driving Q and trying to resolve it in Temperature and time dimensions.

If it is possible, can you let us know how can be it made to work?

I will make it simple to understand.

On a graph,

On longitude axis, I have temperature.

On Latitude axis, I have time

On Altitude axis, I have Q (Heat Flux)

If we plot the data, graph looks like a surface plot in Excel.

Can we perform a transient analysis in this case. Or will it be pseudo steady analysis ? How this needs to be setup?

Any pointers or help in this direction is highly appreciated.
